Subject: [PATCH] Do not process entity loads in CraftChunk#getEntities
|
|
|
|
This re-introduces the issue behind #5872 but fixes #6543
|
|
The logic here is generally flawed however somewhat of a nuance,
|
|
upstream uses managedBlock which is basically needed to process
|
|
the posted entity adds, but, has the side-effect of processing any
|
|
chunk loads which has the naunce of stacking up and either causing a
|
|
massive performance hit, or can potentially lead the server to crash.
|
|
|
|
This issue is particularly noticable on paper due to the cumulative efforts
|
|
to drastically improve chunk loading speeds which means that there is much more
|
|
of a chance that we're about to eat a dirtload of chunk load callbacks, thus
|
|
making this issue much more of an issue
